liu weikai 7adf727950 feat: add walkie monitor topbar indicators

Add LoRa/FSK topbar modulation badges and monitor status handling for walkie talkie mode.

Keep built-in text candidates and small symbol/emoji font baselines aligned with localization specs, and remove the legacy compiled-in CJK font path.

Bitmap Compression Tool

Use the in-repo tool to convert an existing LVGL bitmap font (lv_font_conv output) to LVGL compressed bitmap format (bitmap_format = 2):

./tools/compress_lvgl_bitmap_font.py path/to/generated_lvgl_font.c

The tool validates each glyph via encode/decode round-trip before writing.

External Pack Workflow

Simplified Chinese no longer ships as a compiled-in UI font. The repository now expects Chinese glyph coverage to be generated into external font packs.

The reference bundle lives under:

packs/zh-Hans

Typical flow:

Refresh the ranked Pinyin glyph sources:

python tools/extract_pinyin_chars.py

Generate the core pack subset:

python tools/build_locale_pack_charset.py --pack-root packs/zh-Hans --font-pack-id zh-hans-core

Generate the extension pack subset:

python tools/build_locale_pack_charset.py --pack-root packs/zh-Hans --font-pack-id zh-hans-ext

Generate font.bin files with lv_font_conv using:

font source: tools/fonts/NotoSansCJKsc-Regular.otf
glyph subsets:
- packs/zh-Hans/fonts/zh-hans-core/charset.txt
- packs/zh-Hans/fonts/zh-hans-ext/charset.txt
output format: bin
size: 16
bpp: 2

Copy the pack directories onto the SD card under /trailmate/packs/....
